Finance / Tech spam

I'm trying to find a way to reduce a certain kind of spam that uses 
sensational finance / technology subject lines.  Typically Elon, Trump, 
Tesla etc.   It often slips through my ruleset. I've tried to create 
local email and domain blocklists, as well as keyword rules based on the 
mailing address in the body. Everything changes too frequently to be 
able to keep up.  They're using commercial email services like MailGun, 
SendGrid, or Salesforce. None of the users I  talk to have subscribed to 
this sort of thing, and yet it's not all users that get this.

Any suggestions would be helpful!

Thanks, Kirk
